RESUMO
Groups of oligoclonal immunoglobulin G (IgG) bands were isolated from sera of patients with subacute sclerosing panencephalitis by employing preparative isoelectric focusing. Six IgG fractions containing two to three oligoclonal bands with different isoelectric points were used to precipitate the proteins from Vero cells infected with measles virus. The results showed that all of the measles virus proteins except the M protein were precipitated by all of the IgG fractions and that the precipitation of viral proteins by the fractions containing groups of oligoclonal IgG showed slightly different patterns in some sera, whereas other sera showed no significant differences. The present study indicates that oligoclonal IgGs in subacute sclerosing panencephalitis sera are not specific to individual measles virus proteins.
